Every day, your body replaces billions of cells—and yet, your tissues stay perfectly organized. How is that possible?

A simple, chemical materials model may lead to a better understanding of the structure and organization of the cell according to a researcher.

Simple and complex cells were first defined in the primary visual cortex (V1) of cats according to their distinctive spike receptive-field structures 1. Simple-cell receptive fields are made up of ...

By examining squid skin cells three-dimensionally, a University of California, Irvine–led team has unveiled the structures responsible for the creatures' ability to dynamically change their appearance ...

A previously unknown structure discovered in our cells could pave the way toward new treatments for various genetic disorders ...

In the beginning, there was boredom. Following the emergence of cellular life on earth, some 3.5 billion years ago, simple cells lacking a nucleus and other detailed internal structure dominated ...

Few questions have captivated humankind more than the origin of life on Earth. How did the first living cells come to exist? How did these early protocells develop the structural membranes ...

Although known since the 1830s as a round, dark spot in a cell's nucleus, only recently has the nucleolus gotten its full due. Scientists, including research conducted by the lab of Clifford ...

Analyzing cells or other structures is one of the most challenging tasks for researchers working in microscopy and is an important task for both basic research in biology and medical diagnostics.

The researchers tested the RNA origami in a lipid vesicle, a simple cell model system widely used in biology. Using so-called RNA aptamers, the artificial cytoskeleton was bound to the cell membranes.
